To all 'whom 'it may concern:

Be it known that I, Louis C. IlnxniKsENf, a citizen of the United States, residing at lios Angeles, in the, county of Los Angeles and State of California, have invented new and 'usefulImprovements in Electrical Instantaneous \'Vaterl leaters-7 otl which the following is a specification.

My invention relates to an instantaneous electrical water heater in which a plurality of resistance coils are used to. heat water; and an object thereof is to provide a heater of small and compact form which may be utilized in heating water to the required teni- I accomplish this object iv means of the device described herein and illustrated in the accompanying drawings, in whichz Figure 1- is a central vertical section of my heater taken on line l--l ol' Fig. 2. Fig. .2- is a cross section of my heater taken on line 2 2 of Fig. l. Fig. 3+ is a plan view ol' one of the electrical heating elements. Fig. 4- is a perspective view of my complete device.

Referring to the drawings, 5 designates a metallic casing closed on all sides, the back plate ('i being removable so that ready access may be had to the interior. Arranged within this casing is a waterway 7 which is preferably formed of copper tubing and bent to form a plurality of coils 8; they inlet Stof the waterway enters approximately at the bottoni of the casing and the outlet l0 terminates outside of the casing on the front face thereof. I have illustrated this waterway in thc form of a series of spiral coils, butother arrangements and dispositions maybe iuade without departing from the spirit. of my invention, the main object being to obtain as v long a waterway as is possible and still retain the casing in a small and compact form. The inlet to thowaterway 7 is connected to a soui'ce of supply (not shown) by a llexiible pipe l 1. f'

i cured in a suitable manner yin the iiiterior ol the casing and interposed between the coils 8, as is best. illustrated in Fig. 2 ol the drawings are a plurality of electrical` heating elements l2 preferabl resistance coils, heilig connected together in series and terminating on the outside of thc casing and connected to au electric socket 13 of any glesired forni. 'lhe resistance coils may heronnected to a source of electrical energy (not shown) b v meanslof `plugs 14. The interior of the casing is filled with a heat conserving and electric insulating material 15, preferahlv asbestos as I have found that that material retains the heat. thc longest.

It will be observed that by arranging the coils of the waterway closel)Y together and interposiiig a. resistance between thel adjacent coils I am enabled to appl thc heat generated bv the current passing t irough the coils to the best advantage, thus heating the waterway in the minimum amount of time.

It will be further observed from the. above description that I havel provided a device which is small and compact in forni and one that is portable and which ma he used in various situations, such as kite ien sinks, bath tubs, wash bowls and other places where hot` water is required.

llaving described my invention what I claim as new and desire to secure. by Letters Patent isz- An electrical water` heater comprising a metallic casing, a heat conserving material completely lilling said metallic casing, a water conductor com rising a plurality of coilsf arranged one aliove the other, and spaced apart from each other within said heat-conserving material, an electrical conductor comprising a plurality of coils, one of jsaid coils being positioned adjacent each of the water conductor coils, but spaced therefrom by said heat-conserving material.

ln witness that I claim the foregoing I have hereunto subscribed my name this 2nd day of April, nio?. t'
